6. Suzie hammers on a block of wood when she is 85 meters from a large brick wall. Each time she she hits the block, she hears an echo 0.50 s later. With this information, show that the speed of sound is 340 m/s.

What are the first four resonant frequencies of a 10-cm long tube with (a) Both ends open? (b) Both ends closed? (c) One end open and one end closed?

Wave 1 carries more energy than Wave 2. Wave 3 carries more energy than Wave 2. Keeping speed constant, the greatest amount of energy is carried by a wave with-A a low amplitude and a high frequency. B a low amplitude and a low frequency.
